At Murray's death, his papers passed to his widow, Anna Murray, who made some additions and changes in an attempt to keep the information current. She also continued the unsuccessful search for a publisher and later attempted to sell the manuscripts.
In 1966, eleven years after her death, the Murrays' only surviving son, Harold Baldwin Murray, gave his father's manuscripts and some personal papers to the State Historical Society of Wisconsin.
The original papers, which were so brittle and soiled as to be unusable, were discarded after microfilming.
